BACKGROUND

Proximity payment devices are in widespread use. Many are card-shaped and resemble a standard credit card in appearance although other form factors are also used. It has also been proposed to equip consumer devices, such as wristwatches and the like, with proximity payment capabilities.

A well known standard for proximity payment devices has been promulgated by MasterCard International Incorporated, the assignee hereof, and is referred to as “PayPass”. Proximity payment devices typically include a radio frequency identification (RFID) integrated circuit (IC) embedded in a plastic body or contained in a housing. An antenna is also embedded in the plastic body or housing. The antenna may allow the proximity payment device to receive a power signal from a point of sale terminal. The antenna is also used by the internal circuits to communicate information with the POS terminal, such as the payment account number, and possibly other information as well.

One issue faced by account holders with proximity payment devices is that a wrongdoer may attempt to interrogate proximity payment devices to download account numbers therefrom without their knowledge. It has been proposed to protect against this possibility by preventing proximity payment devices from transmitting the account numbers unless the user is pressing a switch on the device at the time that the device is interrogated. However, if this approach were applied to a proximity payment device provided as a wristwatch, bracelet or wristband, the user would need to engage in an awkward two-handed maneuver to have the device read by the POS terminal.

DETAILED DESCRIPTION

FIG. 1 is a schematic block diagram representation of a proximity payment device 100 according to some embodiments. Referring to FIG. 1, according to some embodiments, the proximity payment device 100 may include a payment subsystem 101, a sensor subsystem 110 and a support structure 102, which may support the payment subsystem 101, the sensor subsystem 110 and/or other components of the proximity payment device 100. In some embodiments, the payment subsystem 101 may comprise an RFID IC, which except as described herein, may operate generally in accordance with conventional practices (such as those contained in the “PayPass” standard) related to exchange of data by a proximity payment device with a point of sale terminal. The sensor subsystem 110 may comprise an accelerometer, a rotation sensor, a velocity sensor a position sensor and/or another type of sensor that senses movement and/or position of the proximity payment device 100. In some embodiments, the sensor subsystem 110 may comprise a sensor that is the same as and/or similar to a sensor typically used in a stepometer. In some embodiments, a position sensor may comprise a mercury switch.

The support structure 102 may comprise a housing, casing and/or plastic body that supports the payment subsystem 101, the sensor subsystem 110 and/or some or all other components of the proximity payment device 100. As used herein, the support structure 102 supports a component of the proximity payment device 100 if the component is at least (i) partially and/or entirely disposed on, disposed in, contained in, mounted on, mounted in, installed on, installed in and/or embedded in the support structure 102 and/or (ii) partially and/or entirely disposed on, disposed in, contained in, mounted on, mounted in, installed on, installed in and/or embedded in a component that is supported by the support structure 102. In some embodiments, the payment subsystem 101 and/or the sensor subsystem 110 may be disposed entirely within the support structure 102.

In operation, the sensor subsystem 110 may sense movement and/or position of the proximity payment device 100 and may provide a signal indicative thereof. As used herein, a signal may be any type of signal, i.e., an analog signal, a digital signal, a single ended signal, a differential signal and/or any other type of signal or combination thereof. The signal may be supplied to the payment subsystem 101, which may determine whether the movement and/or position sensed by the sensor subsystem 110 satisfies a reference criteria. If the movement and/or position satisfies the reference criteria, the payment subsystem 101 may perform one or more functions, which may include enabling operation of the proximity payment device 100. If the movement and/or position sensed by the sensor subsystem 110 does not satisfy the reference criteria, the payment subsystem 101 may perform one or more other functions, which may include disabling operation of the proximity payment device 100.

As used herein the phrase “enabling operation of the proximity payment device” means enabling the proximity payment device to provide information. In some embodiments, the information provided by the proximity payment device may be a payment account number based at least in part on information stored therein. In some embodiments, the information provided by the proximity payment device may be supplied to another device.

If the proximity payment device 100 is enabled for operation, the proximity payment device 100 may, in some embodiments, operate in accordance with a conventional proximity payment device. For example, if the proximity payment device 100 is enabled for operation, the proximity payment device may operate in accordance with the above-mentioned “PayPass” standard. In that regard, the proximity payment device 100 may be presented to a proximity coupling device (not shown in FIG. 1) of a POS terminal (not shown) to accomplish payment for a sales transaction. The proximity coupling device may transmit an interrogation signal. If the proximity payment device 100 is enabled, the payment subsystem 101 may transmit a signal to the proximity coupling device in response to the interrogation signal. One or more signals transmitted by the payment subsystem 101 may include a payment card account number and/or other information required for interaction with the proximity coupling device. In some embodiments, the payment subsystem may transmit the payment card account number and/or other information after a handshake procedure or the like with the POS terminal. The POS terminal may then interact with a payment card system to charge the current sales transaction to the payment card account represented by the payment card account number received from the proximity payment device 100.

If the proximity payment device is worn on and/or carried by one wrist or hand, it may be possible to move and/or position the proximity payment device 100, so as to enable operation of the proximity payment device 100, using the wrist or hand on which the device is worn and/or by which the device is carried, and without the use of the other wrist or hand. This may be helpful if the other wrist or hand is not free. In some embodiments, it may also be possible to present the proximity payment device 100 to a proximity coupling device of the POS terminal using the wrist or hand on which the device is worn and/or by which the device is carried, and without the use of the other wrist or hand. This may also be helpful if the other wrist or hand is not free.

In some embodiments, instead of or in addition to being worn on a wrist, the proximity device may be (i) worn on an arm, hand, finger, neck and/or other part of the user's body and/or (ii) carried in a hand or other part of the user's body and/or in clothing or other article worn and/or carried by the user.

In some embodiments, the proximity payment device 100 may be presented to a proximity coupling device (not shown in FIG. 1) before, during and/or after enabling operation of the proximity payment device 100.

In some embodiments, presenting the proximity payment device 100 to a proximity coupling device may comprise tapping the proximity payment device 100 on a portion of the proximity coupling device (e.g., a designated portion of the proximity coupling device, which may include a transmitter and/or receiver). In some embodiments, the proximity payment device 100 may be presented to a proximity coupling device only by tapping the proximity payment device 100 on a portion of the proximity coupling device (e.g., a designated portion of the proximity coupling device, which may include a transmitter and/or receiver).

In accordance with some embodiments, the sensing of the movement and/or position of the proximity payment device may be initiated prior to presentation to a proximity coupling device. This may permit a greater range of movement and/or positioning and as a result, may permit more flexibility in the choice of reference criteria and/or (ii) may make it possible to sense movement and/or position for a longer duration (which may make it possible to collect more data and/or give a user more time to perform an action or actions) and/or with greater resolution. One or more of the above may contribute to a more effective comparison between sensed movement and/or position and the reference criteria.

In some embodiments, this may be facilitated by providing the power source 114 prior to presenting the device to a proximity coupling device. Thus, the availability of power from a power source prior to presenting the device to a proximity coupling device (i) may permit a greater range of movement and/or positioning of the proximity payment device, and as a result, may permit more flexibility in the choice of reference criteria and/or (ii) may make it possible to sense movement and/or position for a longer duration (which may make it possible to collect more data and/or give a user more time to perform an action or actions) and/or with greater resolution. One or more of the above may contribute to a more effective comparison between sensed movement and/or position and the reference criteria.

In some embodiments a reference criteria may be associated with both enabling operation and disabling operation of the proximity payment device 100. In that regard, in some embodiment, the proximity payment device 100 is enabled for operation if a reference criteria is satisfied a first time and disabled from operation if the reference criteria is satisfied a second time.

In some embodiments, the reference criteria may be satisfied by shaking the proximity payment device 100 at least one time. In that regard, if the sensor subsystem 110 comprises an accelerometer, the reference criteria may be satisfied if the acceleration indicates that the proximity payment device 100 has been shaken at least one time.

In some embodiments, the reference criteria may require that the movement and/or position have a magnitude equal to or in excess of a reference magnitude. Thus, if the sensor subsystem 110 comprises an accelerometer, the reference criteria may require that the acceleration have a magnitude equal to or in excess of a reference magnitude. In some embodiments, the reference magnitude may be chosen to help minimize the possibility of enabling operation of the proximity payment device 100 when the user does not desire to enable operation of the proximity payment device 100.

In some embodiments, the reference criteria may require that the movement and/or position have a profile that matches a reference profile over a duration of time. In some embodiments, the reference magnitude and/or reference profile may comprise a fixed reference magnitude and/or fixed reference profile, respectively. In some embodiments, the reference magnitude and/or reference profile may comprise an adaptively determined reference magnitude and/or reference profile, respectively.

In some embodiments, the payment subsystem 101 may include a data storage circuit 104, an antenna 106, transmit/receive circuitry 108 and/or a control circuit 112. In some embodiments, such data storage circuit 104, antenna 106, transmit/receive circuitry 108 and/or control circuit 112 may be provided in a conventional manner. In some embodiments, the data storage circuit 104 may be a simple memory device capable only of responding to a pre-defined set of commands, or a secure microcontroller capable of executing a pre-defined program. In both instances, these circuits may store the payment account details necessary for the communication with the POS terminal. In accordance with known practices, additional data may be stored in the data storage circuit in some embodiments.

In some embodiments, the antenna 106 may be a loop antenna arranged in and/or supported on the proximity payment device 100. Alternatively, the antenna 106 may be of a different type and/or configuration. In some embodiments, the antenna 106 may be operative to receive interrogation and power signals (which may be the same signal) from a proximity coupling device of a POS terminal and to transmit payment card account number information and/or other information to the proximity coupling device. In some embodiments, the antenna 106 may be operative to receive interrogation and power signals and to transmit payment card account number information and/or other information to the proximity coupling device in accordance with the above-mentioned PayPass standard.

In some embodiments, the transmit/receive circuitry 108 couples the data storage circuit 104 to the antenna 106 to allow the data storage circuit 104 to transmit data signals to the POS terminal via the antenna 106 and/or to receive data signals and/or an interrogation signal from the POS terminal via the antenna 106. Although the transmit/receive circuitry 108 is shown as separate from the data storage circuit 104, in practice the transmit/receive circuitry 108 may be integrated with the data storage circuit 104. For example, the data storage circuit 104 and the transmit/receive circuit 108 may be included in an RFID IC, which is not separately shown in FIG. 1 (In some embodiments, processing may also be included in an RFID IC).

In some embodiments, the control circuit 112 may be operative to receive the signal provided by the sensor subsystem 110 and determine whether a movement and/or a position sensed by the sensor subsystem 110 matches a reference profile.

Still further, in some embodiments, the proximity payment device 100 may include a power source 114, which may be coupled directly or indirectly to, and may supply power to, the control circuit 112, the data storage circuit 104 and also possibly the transmit/receive circuit 108. In some embodiments, the power source 114 comprises a batter. In some embodiments, where the proximity payment device 100 is a wristwatch, the power source 114 may comprise a watch battery, which also supplies power to non-payment-related components (not shown) of the watch.

In some embodiments, the control circuit 112 may be powered by the power source 114 and operative to receive the signal provided by the sensor subsystem 110 and determine whether the movement and/or the position sensed by the sensor matches a reference profile, at times when the proximity payment device 100 is not being interrogated by a POS terminal.

In some embodiments, the payment subsystem 101 may also include a timer circuit 116, which may be coupled to the control circuit 112 to define a period of time of predetermined length commencing with a point in time at which the control circuit 112 detects actuation of the switch 110. The timer may be an electronic circuit that includes a digital counter and/or a circuit of a kind used in a conventional digital watch to measure passage of time. Alternatively, timer circuit 116 may be an electrical circuit that includes a capacitor that is initially charged to start the time period and then is discharged over time to measure out the time period.

In some embodiments, the control circuit 112 and/or the timer circuit 116 may be integrated in an RFID IC (not separately shown in FIG. 1) with the data storage circuit 104 and the transmit/receive circuit 108.

In some embodiments, the control circuit 112 is configured and/or programmed and/or interacts with the data storage circuit 104 and/or the transmit receive circuit 108 such that the proximity payment device 100 is not operative to transmit the device payment account number and/or otherwise to interact with a POS terminal unless and/or until the control circuit 112 determines that the reference criteria is satisfied.

Except as described herein, in some embodiments, the RFID IC may operate generally in accordance with conventional practices (such as those contained in the “PayPass” standard) related to exchange of data by a proximity payment device with a point of sale terminal.

In some embodiments, one or more of the components of the payment subsystem 101 may be selectively enabled/disabled in order to enable and/or disable operation of the proximity payment device 100. In some embodiments, the control circuit 112 may selectively enable/disable one or more of the components and/or selectively couple/not couple components in order to enable and/or disable operation of the proximity payment device 100.

FIG. 2A is a flow chart of a method 200 according to some embodiments. The method 200 is not limited to the order shown in the flow chart. Rather, embodiments of the method 200 may be performed in any order that is practicable. For that matter, unless stated otherwise, any method disclosed herein may be performed in any order that is practicable. Unless stated otherwise, the method 200 may be performed in any manner. In some embodiments, one or more portions of the method 200 may be performed by the proximity payment device 100 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the payment subsystem 101 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the control circuit 112. In some embodiments, one or more portions of the method may be used to enable operation of the proximity payment device 100, disable operation of the proximity payment device 100 and/or perform another function. In some embodiments, one or more portions of the method may be performed while power is applied to the proximity payment device 100. In some embodiments, one or more portions of the method may be performed while power is applied to at least a portion of the embodiment of the payment subsystem 101 illustrated in FIG. 1.

Referring to FIG. 2A, the method may start at 202. At 204, the method may include determining whether a movement and/or a position of the proximity payment device satisfies a reference criteria. In some embodiments, determining whether a movement and/or a position of the proximity payment device satisfies a reference criteria may comprise monitoring a signal provided by the sensor subsystem 110. In some embodiments, the determination may be based at least in part on a signal provided by the sensor subsystem 110. In some embodiments, determining whether the reference criteria is satisfied may comprise determining whether the movement and/or position has a magnitude equal to or in excess of a reference magnitude and/or within a reference range. In some embodiments, determining whether the reference criteria is satisfied may comprise determining whether the movement and/or position has a magnitude having a profile over time that matches a reference profile.

In some embodiments, the reference criteria may require that the proximity payment device be shaken at least one time with a force having a magnitude in excess of a reference magnitude. In some embodiments, the reference criteria may require that the proximity payment device be shaken multiple times with a force having a magnitude in excess of a reference magnitude and within a reference time period.

If the reference criteria is satisfied, then at 206, the method may include performing one or more functions associated therewith. In some embodiments, the one or more functions may include enabling operation of the proximity payment device 100. If at 204 the reference criteria is not satisfied, then at 208, the method may include performing one or more functions associated therewith. In some embodiments, the one or more functions may include disabling and/or or not enabling operation of the proximity payment device 100. In some embodiments, the one or more functions may include not changing the enabled/disabled state of the proximity payment device 100. Thereafter, execution may return to 204.

In some embodiments, the method 200 may include disabling the operation of the proximity payment device 100 unless and/or until the reference criteria is satisfied. The proximity payment device 100 may be considered to be disabled or not enabled so long as it is in this condition.

FIG. 2B is a flow chart of a method 210 according to some embodiments. In some embodiments, one or more portions of the method 210 may be performed at 204 in the method 200 of FIG. 2A. In some embodiments, the method, or one or more portions thereof, may be used in determining whether the movement and/or position has a magnitude having a profile over time that matches a reference profile. In some embodiments, one or more portions of the method 210 may be performed by the proximity payment device 100 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the payment subsystem 101 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the control circuit 112. In some embodiments, one or more portions of the method may be performed while power is applied to the proximity payment device 100. In some embodiments, one or more portions of the method may be performed while power is applied to at least a portion of the embodiment of the payment subsystem 101 illustrated in FIG. 1.

Referring to FIG. 2B, at 212, the method may include determining whether there has been any movement of the proximity payment device 100. In some embodiments, determining whether there has been any movement may comprise monitoring a signal provided by the sensor subsystem 110. In some embodiments, the determination as to whether there has been any movement may be based at least in part on a signal provided by the sensor subsystem 110.

If it is determined that there has not been any movement of the proximity payment device 100, then execution may remain at 212. If it is determined that there has been movement of the proximity payment device, then at 214, the method may include capturing the signal indicative of the movement and/or the position of the proximity payment device 100. In some embodiments, capturing the signal may comprise capturing the magnitude of the signal over a duration of time.

At 216, the method may further include determining whether the captured profile matches a reference profile. If the captured profile matches the reference profile, then the method may include performing one or more functions associated therewith. In some embodiments, the one or more functions may include enabling operation of the proximity payment device 100. In some embodiments, the method may include enabling operation of the proximity payment device 100 for a duration and/or until the account number is transmitted by the proximity payment device 100. In some embodiments, the method may comprise enabling operation of the proximity payment device 100 until the reference criteria is satisfied again.

If the captured profile does not match the reference profile, then the method may include performing one or more functions associated with not matching the reference profile. In some embodiments, the one or more functions may include disabling and/or or not enabling operation of the proximity payment device 100. In some embodiments, the one or more functions may include not changing the enabled/disabled state of the proximity payment device 100.

FIG. 2C is a flow chart of a method 220 according to some embodiments. In some embodiments, one or more portions of the method may performed at 206 in the method 200 of FIG. 2A. In some embodiments, the method, or one or more portions thereof, may be used in enabling operation of the proximity payment device 100 for a time period. In some embodiments, one or more portions of the method 220 may be performed by the proximity payment device 100 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the payment subsystem 101 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the control circuit 112. In some embodiments, one or more portions of the method may be performed while power is applied to the proximity payment device 100. In some embodiments, one or more portions of the method may be performed while power is applied to at least a portion of the embodiment of the payment subsystem 101 illustrated in FIG. 1.

Referring to FIG. 2C, at 224, the method may include enabling operation of the proximity payment device 100 and at 226, the method may further include starting a timer, wherein a time period may be initiated during which the proximity payment device 100 may remain in the enabled condition.

In accordance with some embodiments, the control circuit 112 may start the timer, which may comprise the timer circuit 116 (FIG. 1). With the start of the time period, the timer circuit 116 may be initialized to measure out, and thereby determine a concluding end point of, the time period. For example, a counter circuit (which may be part of the timer circuit 116 but is not separately shown) may be caused to start counting up from zero by counting clock pulses (from a clock circuit which is not separately shown) and the count value of the counter circuit may be compared with a fixed value to determine when the count value has reached the fixed value, thereby indicating the end of the time period. In some embodiments, the length of the time period may be 20 seconds.

At 228, the method may further include determining whether an interrogation signal is received from a POS terminal (not shown). If so, at 230, the account number for the device payment account and/or other information may be sent to the POS terminal via the antenna 106. This may be done, for example, as part of an exchange of communications between the proximity payment device 100 and the POS terminal.

In some embodiments, after the account details or other information is sent at 230, the execution may return to 204 of method 200 (FIG. 2A). In other words, in the method 220 illustrated in FIG. 2C, the proximity payment device 100 may be disabled upon sending of the account number, and may remain disabled until the reference criteria is satisfied again at 204 of method 200 (FIG. 2A). Thus, in some embodiments, the proximity payment device 100 can be read at most once, after each time that the reference criteria is satisfied.

However, in an alternative embodiment, the method 220 illustrated in FIG. 2C may be modified such that execution returns to 228. In such embodiment, the proximity payment device 100 may continue to be enabled to be read until the time period initiated at 226 comes to an end.

At 232, the method may include determining whether the time period has come to an end. In some embodiments, the determination at 232 may be part of a loop with decision block 228 and may be performed before, after or essentially simultaneously with decision block 228. In such embodiments, the loop of decision blocks 228, 232 may continue until either the account number is sent or the time period expires. If it is determined at 232 that the time period has expired, then execution may return to 204 of method 200 (FIG. 2A). In some embodiments, the method may include disabling the operation of the proximity payment device 100 unless and/or until the reference criteria is satisfied again. In that regard, in some embodiments, the method may include, at 204, idling in the condition in which it is not enabled to transmit the account number so long as the reference criteria is not satisfied.

In some embodiments, with this arrangement of the proximity payment device 100, it may be operated in the following manner. With the device worn on one wrist of the user, the user may perform one or more actions that cause the movement and/or position of the proximity payment device 100 to satisfy a reference criteria. The proximity payment device 100 may be enabled and the user may then (or earlier) place the wrist with the device on it next to (or at any position that is suitable relative to) the proximity coupling device of the POS terminal to have the device read during the time period initiated by actuation of the switch.

In some embodiments, the proximity payment device 100 may include information for more than one payment service. In that regard, in some embodiments, the proximity payment device 100 may include information for a debit account, a credit account and/or a transit ticket.

FIG. 2D is a flow chart of a method 240 according to some embodiments. In some embodiments, the method, or one or more portions thereof, may be used if the proximity payment device 100 includes information for more than one payment service. In some embodiments, one or more portions of the method 240 may be performed by the proximity payment device 100 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the payment subsystem 101 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the control circuit 112. In some embodiments, one or more portions of the method may be performed while power is applied to the proximity payment device 100. In some embodiments, one or more portions of the method may be performed while power is applied to at least a portion of the embodiment of the payment subsystem 101 illustrated in FIG. 1.

Referring to FIG. 2D, at 242, the method may include determining whether a movement and/or a position of the proximity payment device satisfies a first reference criteria. In some embodiments, the first reference criteria may require that the proximity payment device be shaken three times with a force having a magnitude in excess of a reference magnitude and within a reference time duration. Thus, if the sensor subsystem 110 comprises an accelerometer, the reference criteria may require that the acceleration indicate that the proximity payment device has been shaken three times with a force having a magnitude in excess of a reference magnitude and within a reference time duration.

If the first reference criteria is satisfied, then at 244, the method may include performing a first function associated therewith. In some embodiments, the first function may include enabling operation of the proximity payment device 100 for use in association with a first payment service, e.g., a debit account. In some embodiments, the first function may also include disabling operation of the proximity payment device 100 for use in association with other payment services. Execution may then return to 242.

If at 242, the first reference criteria is not satisfied, then at 246 the method may further include determining whether movement and/or a position of the proximity payment device satisfies a second reference criteria. In some embodiments, the second reference criteria may require that the proximity payment device be shaken two times with a force having a magnitude in excess of a reference magnitude, within a reference time duration.

If the second reference criteria is satisfied, then at 248 the method may include performing a second function. In some embodiments, the second function may include enabling operation of the proximity payment device 100 for use in association with a second payment service, e.g., a credit account. In some embodiments, the second function may also include disabling operation of the proximity payment device 100 for use in association with other payment services. Execution may then return to 242.

If at 246, the second reference criteria is not satisfied, then at 250 the method may further include determining whether movement and/or a position of the proximity payment device satisfies a third or nth reference criteria. In some embodiments, the third or nth reference criteria may require that the proximity payment device be shaken one time with a force having a magnitude in excess of a reference magnitude.

If the third reference criteria is satisfied, then at 252 the method may include performing a third or nth function. In some embodiments, the third or nth function may include enabling operation of the proximity payment device 100 for use in association with a third payment service, e.g., a transit ticket. In some embodiments, the third or nth function may also include disabling operation of the proximity payment device 100 for use in association with other payment services. Execution may then return to 242.

If at 250, the third reference criteria is not satisfied (i.e., neither the first reference criteria, nor the second reference criteria nor the third reference criteria is satisfied), then at 254, the method may include performing one or more functions associated with not satisfying either of the first, second and third reference criteria. In some embodiments, the one or more functions may include not changing the enabled/disabled state of the proximity payment device 100. In some embodiments, the one or more functions may include disabling and/or or not enabling operation of the proximity payment device 100. Execution may then return to 242.

In some embodiments, the method may be extended to include any number of reference criteria and any number of functions associated therewith.

In some embodiments, the method 200 may further include disabling the operation of the proximity payment device 100 unless and/or until at least one of the reference criteria is satisfied. The proximity payment device 100 may be considered to be disabled or not enabled so long as it is in this condition. In some embodiments, enabling operation of the proximity payment device 100 for use in association with a payment service may include enabling such operation for a duration and/or until information associated with the payment service is transmitted by the proximity payment device 100. In some embodiments, the method may comprise enabling operation of the proximity payment device 100 for use in association with payment service until the proximity payment device 100 is enabled for operation in association with another payment service.

FIG. 2E is a schematic representation of the magnitude of a signal that may be provided by a sensor subsystem 110 in response to shaking the proximity payment device 100 one time, with a force having a magnitude in excess of a reference magnitude and within a reference time duration, in accordance with some embodiments. Referring to FIG. 2E, in accordance with some embodiments, the signal may have a magnitude 260 that varies over time. At an initial time t0, the signal may have a magnitude, e.g., approximately zero, that is less than a first reference magnitude 262 (which may be a positive reference magnitude) and less than a second reference magnitude 264 (which may be a negative reference magnitude). At a first time, e.g., t1, the magnitude may begin to increase and at a second time, e.g., t2, the magnitude may be equal to the first reference magnitude. The magnitude may increase further and may then begin to decrease. The magnitude may exceed the first reference magnitude until a third time, e.g., t3. The magnitude may decrease further and may then increase (i.e., in a negative direction). At a fourth time, e.g., t4, the magnitude may be equal to the second reference magnitude. The magnitude may increase further and may then begin to decrease. The magnitude may exceed the second reference magnitude until a fifth time, e.g., t5. The magnitude may decrease further and at a sixth time, e.g., t6, may have a magnitude, e.g., approximately zero, that is less than the first reference magnitude and less than the second reference magnitude.

In some embodiments, the number of times that the magnitude crosses a reference magnitude may indicate the number of times that the proximity payment device was shaken with a force having a magnitude in excess of the reference magnitude. In this embodiment, the magnitude indicates that the proximity payment device was shaken one time with a force having a magnitude in excess of the first magnitude within a time duration of t0-t60.

Notably, shaking is not limited to the shaking schematically represented by the magnitude represented in FIG. 2E. In some embodiments, the magnitude may exceed a positive reference magnitude without exceeding a negative reference magnitude. In some embodiments, the magnitude may exceed a negative reference magnitude without exceeding a positive magnitude. In some embodiments, the magnitude may or may not vary smoothly over time, may or may not be sinusoidal, may or may not be periodic and may or may not have symmetry.

FIG. 2F is a schematic representation of a waveform of a signal 266 that may be provided by a sensor subsystem 110 in response to shaking the proximity payment device 100 two times, with a force having a magnitude in excess of a reference magnitude within a reference time duration, in accordance with some embodiments.

FIG. 2G is a schematic representation of a waveform of a signal 268 that may be provided by a sensor subsystem 110 in response to shaking the proximity payment device 100 three times, with a force having a magnitude in excess of a reference magnitude and within a reference time duration, in accordance with some embodiments.

FIG. 2H is a schematic representation of the magnitude of another signal that may be provided by a sensor subsystem 110 in response to shaking the proximity payment device 100 with a force having a magnitude less than a reference magnitude, according to some embodiments. Referring to FIG. 2H, in accordance with some embodiments, the signal may have a magnitude 270 that varies over time. However, the magnitude remains less than the first reference magnitude and greater than the second reference magnitude.

In some embodiments, the user may be provided with the option to define one or more reference criteria. In some embodiments, this may be done via a user interface. In some embodiments, a user interface may comprise a graphical user interface. In some embodiments, the user may be provided with the option to define one or more biometric reference criteria.

FIG. 2I is a flow chart of a method 280 according to some embodiments. In some embodiments, the method 280, or one or more portions thereof, may be used in defining one or more reference criteria. In some embodiments, one or more portions of the method 240 may be performed by the proximity payment device 100 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the payment subsystem 101 or one or more portions thereof. In some embodiments, one or more portions of the method may be performed by the control circuit 112. In some embodiments, one or more portions of the method may be performed while power is applied to the proximity payment device 100. In some embodiments, one or more portions of the method may be performed while power is applied to at least a portion of the embodiment of the payment subsystem 101 illustrated in FIG. 1

Referring to FIG. 2I, at 281, a user may access the system. At 282, the user may be prompted (e.g., via a user interface) to enter a user identifier (e.g., a password or personal identification number (PIN)). If the user enters a user identifier, then at 283, the method may further include determining whether the user identifier is valid. If the user identifier is valid, then at 284 the method may include prompting the user to indicate whether a reference criteria is to be defined (e.g., initially and/or changed). At 285 the method may include determining whether a reference criteria is to be defined (e.g., initially and/or changed). If a reference criteria is not to be defined (e.g., initially and/or changed), then at 286, the method may end.

If a reference criteria is to be defined (e.g., initially and/or changed), then at 287, the method may include prompting the user to define the reference criteria.

In some embodiments, the user may define the reference criteria using one or more input devices in and/or on the proximity payment device 100. Thus, the method may include receiving the reference criteria via one or more input devices. In some embodiments, the one or more input device(s) may comprise the sensor subsystem 110.

In some embodiments, the user may define a reference criteria, at least in part, by training the proximity payment device 100. That is, the user may move and/or position the proximity payment device 100 to indicate a desired reference profile. The proximity payment device 100 may capture the profile of the signal provided by the sensor subsystem 101 in response to the desired reference profile.

FIG. 2J is a schematic representation of a magnitude of a signal that may be provided by a sensor subsystem 110 in response to movement and/or positioning provided by the user. Referring also now to FIG. 2J, in accordance with some embodiments, the signal may have a magnitude 292 that varies over time. In this embodiment, the magnitude 292 indicates that the proximity payment device was shaken two times with a force having a magnitude in excess of the first magnitude 262 within a time duration T. Notably, the reference profile provided by the user is not limited to the profile schematically represented in FIG. 2J. In some embodiments, the reference profile may or may not vary smoothly over time, may or may not be sinusoidal, may or may not be periodic and may or may not have symmetry.

In some embodiments, a reference criteria may be based at least in part on the captured profile. In some embodiments, the reference criteria may be equal to the captured profile. Such reference criteria is a type of biometric reference criteria and/or biometric reference profile. In some other embodiments, the method may include defining a range, e.g., range R, disposed about the captured profile, to thereby define a window W that may define the reference criteria. Such reference criteria is a type of biometric reference criteria and/or biometric reference profile.

At 288, the method may further include determining whether the reference criteria is valid. If the reference criteria is not valid, then at 289 the method may include informing the user of such and execution may return to 287. If the reference criteria is valid, then at 290, the method may include storing the reference criteria.

Notably, the range may or may not be uniform along the profile and may or may not be disposed symmetrically about the captured profile. Moreover, the larger the range, the easier it will be for a user (authorized or unauthorized) to move and/or position the proximity payment device 100 in a manner that matches the reference criteria. The smaller the range, the more difficult it will be for a user to move and/or position the proximity payment device 100 in a manner that matches the reference criteria.

In some embodiments, the user may decide to change the reference criteria if the user forgets the reference criteria and/or if information regarding the reference criteria is obtained by an unauthorized user.

In some embodiments, the movement and/or positioning provided by the user to train the proximity payment device 100 may comprise movement and/or positioning used to present the proximity payment device 100 to a proximity coupling device of a POS terminal. In such an embodiment, the reference criteria may be satisfied when the proximity payment device 100 is presented to a proximity payment device. Use of such reference criteria may eliminate the need to satisfy an reference criteria prior to presenting the proximity payment device to the proximity coupling device.

In some embodiments, the proximity payment device 100 may be a stand alone device. In some embodiments, the proximity payment device may be combined with another device, which may include but is not limited to a wristwatch, a keyfob, a mobile telephone, a portable music player and/or a portable data assistant (PDA). The combined device is sometimes referred to herein as a proximity payment device.

The electrical interface 724 may include first and second contacts 728, 730, which may be adapted to contact the contacts 508, 510, respectively, of the IC 500 of the small IC card 400.

A switch 731 may be electrically connected in series between the contacts 728, 730 and the antenna 106. The switch 731 may have an open position and a closed position. With the switch 731 in the closed position, the antenna 106 is electrically connected to the first and second contacts 728, 730 to thereby electrically connect the antenna 106 to the contacts 508, 510, respectively, of the RFID IC 500. With the switch 731 in the open position, the antenna 106 is not electrically connected to the first and second contacts 728, 730 or the contacts 508, 510 of the RFID IC 500.

Thus, the transmit/receive circuitry 108 may be able to transmit the device payment account number and/or otherwise to interact with a POS terminal if the switch 731 is in the closed position. On the other hand, the transmit/receive circuitry 108 may be unable to transmit the device payment account number and/or otherwise to interact with a POS terminal if the switch 731 is in the open position.

Notably, the terms “open position” and “closed position” are not meant to imply that switch 731 is limited to a mechanical switch. In some embodiments, the switch 731 may comprise a transistor and/or other active device(s) and may have an “on state” and an “off state” in lieu of and/or in addition to an “open position” and “closed position”.

The contacts 728, 730 may be biased (e.g., in the z direction) so as to help insure contact with respective contacts of the IC 500 of the small IC card 400. In some embodiments, each of the contacts 728, 730 may comprise a spring contact that includes a contact and a spring integral therewith to bias the spring contact (e.g., in the z direction).

The control circuit 112 may be electrically connected to and/or may control the switch 731 that is electrically connected in series between the contacts 738, 740 and the power source 735. In some embodiments, the control circuit 112 (FIG. 1) may be operative to close the switch 731 to enable operation of the proximity payment device 100 and to open the switch 731 to disable operation of the proximity payment device 100.

The controller 735 may or may not be electrically connected to and/or control any other components (e.g., a movement (not shown) of the wristwatch 300.

In some embodiments, the transmit/receive circuitry 108 may be unable to transmit the device payment account number and/or otherwise to interact with a POS terminal unless the IC 500, the data storage circuit 104 (FIG. 1) and/or the transmit/receive circuit 108 (FIG. 1) receive electrical power from the power source 734.

In that regard, in some embodiments, the switch 731 may be electrically connected in series between the power source 734 and the IC 500, the data storage circuit 104 (FIG. 1) and/or the transmit/receive circuit 108 (FIG. 1). With the switch 731 in the closed position, the power source 734 is electrically connected to the IC 500, the data storage circuit 104 (FIG. 1) and/or the transmit/receive circuit 108 (FIG. 1) are electrically connected to the power source 734, as may be required to transmit the device payment account number and/or otherwise to interact with a POS terminal. Otherwise, the proximity payment device 100 may be disabled. In some embodiments, the control circuit 112 (FIG. 1) may be operative to close the switch 731 to enable operation of the proximity payment device 100 and to open the switch 731 to disable operation of the proximity payment device 100.

In some embodiments, the RFID IC 500 may further include the control circuit 112 (FIG. 1), the timer circuit 116 (FIG. 1) and the switch 731.

If divided into blocks, the amount of information in a block may be predetermined or determined dynamically, and/or may be fixed (e.g., uniform) or variable. A communication link may employ a protocol or combination of protocols including, for example, but not limited to the Internet Protocol.

In accordance with some embodiments, the proximity payment device 100 may be presented to a proximity coupling device by positioning the proximity payment device 100 in physical contact with the proximity coupling device.

FIG. 9 is a schematic perspective view of a proximity payment device being presented to a proximity coupling device in accordance with some embodiments. Referring to FIG. 9, in some embodiment, the proximity payment device 100 may be presented to a proximity coupling device 900 by tapping a portion of the proximity payment device 100 on a portion of the proximity coupling device (e.g., a designated portion 902 of the proximity coupling device, which may include a transmitter and/or receiver).

However, in some embodiments, the proximity payment device 100 may be presented to a proximity coupling device 900 by positioning the proximity payment device within range of the proximity coupling device so as to permit wireless communication between the proximity payment device 100 and the proximity coupling device 900, which in some embodiments may not require positioning the proximity payment device 100 in physical contact with the proximity coupling device.

In some embodiments, lettering (not shown) or other symbols (not shown) may be present on the front surface 1412 of the card-shaped body 1402 and/or on the rear surface (not shown) of the card-shaped body 1402. The proximity payment card 100 may have one or more magnetic stripes (not shown) on the card-shaped body 1402 to allow the proximity payment card 100 to be read by a magnetic card reader. In addition, or alternatively, there may be embossed numbers and/or letters on the card-shaped body to indicate one or more account numbers and/or the name of the holder of the proximity payment card 100. In addition, or alternatively, non-embossed printing on the front surface 1412 may indicate the account numbers and/or the holder's name. Still further, the front surface 1412 of the card-shaped body 1402 may carry one or more logos and/or brands, including for example the brand/logo of a national payment card association such as MasterCard International Incorporated. The brand/logo of the issuer may also be present, as well as, for example, a specific card product brand. Other conventional features that may be present on the proximity payment card 100 (though such features are not shown) are an adhesive paper strip to receive the signature of the cardholder, and a security code or the like printed on the adhesive strip.

In some embodiments, as an alternative to powering some or all of the circuitry shown in FIG. 1 from a battery to allow the control circuit 112 to detect actuation of the switch, the circuitry may instead be powered by a storage capacitor that has been suitably charged. In addition or alternatively, the time period for enablement of the proximity payment device may be measured out by a capacitor that is charged to start the time period, and then discharges to measure out the time period. The state of the latter capacitor may be monitored by, e.g., the control circuit 112 to determine whether the proximity payment device 100 should respond to any interrogation signal that it may receive.

In another embodiment, the switch 110 may be coupled to a processing/control circuit (not shown) that is separate from the data storage circuit 104 and the transmit/receive circuit 108. For example, the switch may be coupled to the control circuit used for controlling other functions in the device (such as wristwatch functions). In response to the switch being actuated, the control circuit may enable the RFID IC for a payment transaction for a measured time period. In this case, the payment aspects of the device may be powered entirely by the interrogation signal from the POS terminal.

In some embodiments one or more of the circuits of the proximity payment device may include an enable line that may be used to enable and/or disable the proximity payment device. In some embodiments, methods in addition to and/or in lieu of those described herein may be employed to enable and/or disable the proximity payment device.

The proximity payment device may be a wristwatch, a wristband, a bracelet, a pendant or may be in another form. Consequently, the housing 102 may be the case of a wristwatch, a wristband, a bracelet, a pendant or another form.
